The easiest and most low-tech way to check, is using a 9Volt battery (you know the type with the contacts both at the same end). Hold the old speaker in one hand (with your hand on the cone) and touch the battery contacts onto the electrical contacts of the speaker. When the Cone Moves out, the contact with the battery positive on is the positive contact of the speaker. If you mark one of the wires and the contact it came off, you now know what wire does what.
